It is very difficult to separate taste from odor because these two human senses are so closely related. Most occurrences of a peculiar taste or odor in the water can be grouped into one of the following three categories: (1) chlorinous, bleachy, chemical, and medicinal; (2) sulfurous (rotten egg-like), decayed, and sewage-like; or (3) musty, moldy, or earthy.
A common cause for a chlorinous, bleachy, chemical, or medicinal taste or odor in the water: the small addition of chlorine to the water by the District to make sure that the water is clean and safe to drink.
Two common causes of a sulfurous decayed, or sewage-like taste or odor in the water are bacteria growing in your drain or bacteria growing in your water heater.
A common cause of a musty, moldy, or earthy taste or odor in the water is bacteria growing in your drain.
